BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a kit that is used to convert a stockof a bolt-action rifle.

2. Description of Related Art

A rifle is a commonly used firearm that is used for hunting or sportingpurposes. The rifle is used primarily due to its accuracy and rangewhich is superior to the use of a hand gun. Rifles come in a variety ofcalibers and styles depending on the use and application thereof. Riflesare widely used in the military and many such rifles are characterizedas automatic or semi-automatic rifles. In automatic and semi-automaticrifles the shells are loaded into the firing chamber of the rifle andunloaded automatically. The semi-automatic and automatic rifles have thecapability of attaching magazines which hold numerous shells andtherefore are ideal for military situations where numerous rounds mustbe fired in a short period of time. Rifles used for hunting may also beautomatic but usually have less ammunition capacity. One popular rifleused by hunters and marksman is a bolt-action style rifle. Thebolt-action style rifle is manually loaded and unloaded through the useof a bolt-action mechanism.

Bolt-action rifles are particularly useful for target and sniper typeshooting. The bolt-action rifle is operated by manually opening andclosing the breech with a small handle, which is commonly placed on theright side of the weapon. When the bolt is unlocked the breech is openedand the shell casing is withdrawn or ejected. A new round or shell isplaced in the breech and the bolt is closed. Although the bolt-actionrifle has a slower rate of firing it is still considered a more accurateweapon as opposed to the automatic and semi-automatic weapons.

Most bolt-action rifles come with a standard straight grip stock thatproceeds slowly from the toe to the trigger and therefore is fairlyhorizontal near the trigger handle. Some gunstocks for bolt-actionrifles have been modified to provide some hand gripping curvaturefeatures. One difference between a bolt-action rifle and thesemi-automatic or assault rifle is that most assault rifles have apistol type grip where a separate grip is provided just behind thetrigger for a pistol type gripping action. The pistol grip offers manyadvantages in the control of recoil and is preferred by many targetshooters for it's trigger control. Many of the stocks used on theassault rifles are sliding and adjustable or a separate piece from thegrip provided on the rifle.

It therefore may be advantageous to have an assault type stock with apistol grip on a bolt-action style rifle. Consequently, it would beadvantageous to have a kit that could convert the standard stock from abolt-action rifle to an assault style grip with assault style stock.

SUMMARY OF THE INVENTION

The present invention relates to a butt stock conversion kit forconverting a bolt-action rifle stock comprising: an assault type stock,wherein said assault type stock includes a threaded end and an adjustingbolt; a bushing, where said bushing connects the butt stock to areceiving section of a bolt-action rifle; a grip plate where said gripplate receives a hand grip and said grip plate is positioned behind thetrigger guard of the rifle; and a means to secure the grip plate on tothe receiving section of the rifle. The means to secure the grip plateincludes at least one bolt connecting the plate to the rifle. Thereceiving section of the rifle may include a threaded end to attach thebushing thereto. The rifle includes a cavity to receive the grip plate.The hand grip may also include an opening to receive the grip plate.

DETAILED DESCRIPTION

The present invention provides a gun stock conversion kit that iscapable of converting a standard stock on a bolt-action rifle into anassault style stock with a pistol grip. The present invention includesan assault style stock that is inserted onto a bolt-action rifle alongwith a piston grip to convert the standard stock of a bolt-action rifleinto an assault style stock. Referring to FIG. 1, a butt stockconversion kit 100 is depicted. The butt stock conversion kit 100includes a butt stock 30 that further includes a buffer tube 32 with athreaded end 34. The threaded end 34 is connected to the receiving endof a bolt-action rifle 50 by using a bushing 20. The kit furtherincludes a pistol style grip 25. This conversion kit is inserted onto abolt-action rifle and therefore it converts the standard stock into theassault style stock on the bolt-action rifle.

A detailed look at some of the components of the butt stock conversionkit is depicted in FIG. 2. The buffer tube 32 includes a bolt 35 thatprovides a means of adjusting and tightening the stock 30 onto thebushing 20. The grip 25 is attached to the underside of the rifle 50just behind a trigger guard 52. A grip plate 40 is provided for theinsertion of the grip 25 onto the rifle 50. A top bolt 42 is insertedthrough the topside of the receiving end of the rifle 50 and penetratesthere through to attach the grip plate 40 into place. A second bolt 44extends into the grip 25 and is used to attach the grip onto the gripplate 44.

FIG. 3 provides a view of the various components completely detachedfrom the rifle 50. As shown, the bushing 20 attaches to a threaded end55 of the bolt-action rifle 50. The bushing 20 inserts onto thisthreaded end 55 and also receives the butt stock 30 at the opposite endof the bushing 20. Further shown is the grip plate 40 completely removedfrom the bolt-action rifle 50. The grip plate 40 is configured in amanner so that a section of the grip plate inserts into an opening ofthe bolt-action rifle and therefore receives the top bolt 42 to securethe grip plate 40 into place. The bottom portion of the grip plate 40inserts into an opening provided in the grip 25 to receive the gripplate 40. Once the components are all placed together the stock iscompletely converted with a pistol style grip 25 and an assault actionstyle stock 30.

FIG. 4 depicts a close up of the top portion of the rifle 50 at thereceiving end to show an opening 51 for the insertion of bolt 42. Theopening 51 provides the means to insert the bolt 42 in order to bolt thegrip plate 40 into place. The bolt 42 inserts into the top opening shownin the grip plate 40. FIG. 5 depicts the bottom of the rifle 50 thatreceives the grip plate 40. A grip plate receiver 53 is shown that has abolt opening 54 which is the opposite end of the opening 51 shown inFIG. 4. The bolt 42 inserts into the top opening 51 and extends out intothe opening 54 for insertion into the top opening of the grip plate 40.The bottom of the grip plate 40 inserts into an opening 27 provided onthe grip 25. Once the grip 25 is inserted on the grip plate 40, bolt 44extends into a bolt opening not shown in the grip 25 that allows for theinsertion of the grip 25 onto the grip plate 40.

The butt stock conversion kit according to the present inventionprovides the means to re-assemble and convert the standard stock of abolt-action rifle into a semi-automatic or assault style stock withpistol grip. By using an assault style stock grip, the user may modifythe rate of fire of the bolt-action rifle and have the convenience of anassault style stock with grip for use there with. The kit is designed soit may be used with any bolt-action style rifle and is easy to assembleand to convert the rifle grip and stock areas.
